The purpose of this activity is to measure air pressure. Students record atmospheric pressure using a barometer or altimeter. Intended outcomes are that students gain an understanding that barometric or altimeter pressure varies and its increase or decrease indicates an upcoming change in the weather. Students also learn that the air has weight. Supporting background materials for both student and ... Full description.

This resource provides instructions on how to log atmosphere data using a Rainwise weather station. A weather station is setup to measure and record atmospheric measurements at 15-minute intervals and can be transferred to the GLOBE program via email. Students can view data for their school that are continuous and show variations within a day. The data collected includes wind speed and direction and ... Full description.

The purpose of this activity is to discover why an instrument shelter is built the way it is. Students construct shelters that have varying properties and place them in the same location or place similar shelters in different locations and compare temperature data taken in each shelter. Students should predict what will happen for each of the different shelter designs or placements and perform the ... Full description.

The purpose of this activity is to measure surface temperature with a handheld Infrared Thermometer (IRT). The instrument is pointed at the ground to take surface temperature readings. Intended outcomes are that students will learn to use an infrared thermometer, and understand how different surfaces radiate energy. Supporting background materials for both student and teacher are included. Full description.

The purpose of this resource is to determine the transparency of water. Students measure water transparency at their undisturbed study site using a transparency tube or Secchi disk. Full description.

The purpose of this resource is to measure the temperature of a water sample. Students use an alcohol-filled thermometer or meter to measure the temperature of water. The meter requires calibration before use; the accuracy of the thermometer needs to be checked before use. Full description.

The purpose of this activity is to measure the total precipitable water vapor (column water vapor) in the atmosphere above an observer's site. Students point a GLOBE/GIFTS water vapor instrument at the sun and record the voltage readings from a digital voltmeter. They observe sky conditions near the Sun and perform the Cloud Protocols. Intended outcomes are that students understand the concept that ... Full description.
